After 25 years, my Concord home needed a full HVAC replacement. I did my homework -- four quotes,…read moreverified equipment certifications, asked hard questions about duct sealing, zoning, and equipment sizing before deciding. A-1 answered every question confidently, corrected a spec error in their own quote when I caught it, and put everything in writing before I signed. Install day: Austin, Joey, and Edgar showed up on time. Floors covered, shoes covered, house treated well. Two days -- day one removal and new equipment, day two ductwork and zoning. Heating and cooling tested before they left. Full documentation handed over on the spot. No hidden charges, no surprises, no change orders. Price was mid-range among four quotes, but the warranty structure -- lifetime workmanship, no-lemon guarantee, payment at completion -- made it the best overall package. Still have HERS test-out and city inspection scheduled, but based on every step of this process I'd recommend A-1 without hesitation. Austin, Joey, and Edgar did a great job.

They used rugs to protect our floors and made sure to clean up after themselves. When they left, the house looked just as clean as before they started. Highly recommend Carlos and his team if you're looking for quality work and great service!

We cannot say enough good things about Attic Pros! From start to finish, it was a great experience…read more We initially called for attic, crawl space and duct cleaning, as well as rodent proofing (sealing vents, etc). Samim came out and did a very thorough evaluation, showing us dozens of photos of areas that needed attention. He also recommended new insulation, which we hadn't considered and told us our dryer vent needed repair. It took us a few weeks to schedule, during which time Samim followed up periodically, never pushy, always answering our questions and providing more info. His professionalism and knowledge was a huge reason why we chose to work with Attic Pros. On the day of the job, Osman and crew cleaned the attic and crawl space and installed new installation, while Douglas repaired the dryer vent and Kevin cleaned the ducts. They did an amazing job sealing off the work areas and keeping the house clean, despite it being very messy and grueling work! They spent about 3 hours vacuuming the attic and another half a day sweeping the crawl space by hand. Their attention to detail was above and beyond what we expected. We were sooo impressed! And Samim's recommendations were spot on - our dryer is much more efficient now and we noticed the house was cooler within hours of the new insulation being installed (it was the height of summer). We'd use and recommend them again and again!

We had a serious rat problem that left our home in quite a mess, and they did an excellent job taking care of everything. They sealed all potential entry points, cleaned up the affected areas, and installed new insulation. The entire process was efficient, well organized, and handled with great care. Sean was especially helpful in explaining every step of the process in detail and patiently answering all of my questions. Whenever I had a concern, he was very responsive and addressed it quickly. I also really appreciated how transparent and reasonable their pricing was. The estimate was clearly explained upfront, including any potential uncertainties that could affect the final cost. Even with those variables, the final price stayed very close to the original estimate and well within a reasonable range, which gave us a lot of peace of mind. The whole project was very well managed. After each stage, they provided photos or videos showing the completed work, so we always knew exactly what had been done. Their follow-up after the project was also excellent. Overall, we had a great experience with Sean and his team. They are professional, reliable, transparent, and genuinely care about doing the job right. I would highly recommend them!

I would say, they did an excellent job - Starting with Jeremy, who accommodated my schedule for preliminary inspect and gave me a on the spot quote. Elder and the guys did an excellent job in covering up the entire house and finished the job in 2 days. My house had no insulation in the walls- to very less in the attic. After the insulation my Heat as well as Cold is retained inside the house. Heat turns on once in a 24 Hr cycle vs multiple times in an hour previously. If you are thinking of in wall insulation, it's totally worth it. The quote was the most competitive and they were very flexible. I am still closing out the multiple holes in the wall, will take time as i prefer to do it myself- I had plans to paint anyway .

I was initially impressed with what seemed like a thorough and well-considered estimate. It felt…read morelike the team really evaluated my attic and cooling needs. The addition of two QuietCool fans also seemed like a major plus, as I was already familiar with the product and expected it would significantly help with cooling. When it came to the insulation work, I was very pleased. The crew did an excellent job removing the old insulation and installing the new. They worked efficiently, protected my floors well, and ensured that no insulation debris entered the living areas. That part of the job was handled professionally. However, I was less impressed with the radiant barrier installation. This may partly be due to a misunderstanding on my end, as I expected a different type of material, but the end result did not meet my expectations. The biggest issue, unfortunately, was the installation of the fans. At best, it was very poorly executed. The fans are 16" units with 12" duct openings, yet they were installed directly against the gables, which severely restricts airflow. Proper installation should have included a box or shroud to help direct airflow effectively through the fans. Because of this poor airflow, the fans do not cool the attic--in fact, they appear to make things worse. I can actually watch the temperature on the thermostat increase when the fans are turned on. I reached out to my representative multiple times, but the response was disappointing. I was told they could not take the fans back, and when I asked why the attic temperature increases when they are running, I was told there was no explanation and nothing further could be done. As temperatures continue to rise, I'm left frustrated that I spent $1,200 on two fans that perform the opposite of what was promised, with no meaningful support or resolution offered. UPDATE: After posting my initial review, I was contacted by both the project manager and the owner. I reiterated the reasons for my frustration, explaining that my review reflected my honest impression of what I saw as a lack of clear communication and effective management of the project and customer expectations. The project manager apologized for the communication breakdown and asked if I would be open to giving them an opportunity to make things right. A technician was then sent out, and he took the time to fully understand the issue, carefully examine the installation, and make several adjustments to the original work. He believes these changes will help improve airflow in the attic. Since my attic has some unique characteristics, he also provided helpful suggestions for additional ways to improve cooling and airflow--something I feel should have been addressed during the initial planning stage of the project. Whether these changes will result in significant improvement remains to be seen; I'll have a better sense once the weather warms up. I do appreciate the follow-up and the willingness of the project manager to reach out and try to make things right, and I have updated my review accordingly. That said, I want to be clear that the increase in my rating is largely due to the technician and the time he invested in evaluating the full situation, as well as both implementing and proposing thoughtful solutions.

The before and after pictures were very detailed and everything looked great, beat my expectations. Thanks again to Ruben and his team.
